I like Jenkins best because it makes build, test, and deployment automation reliable and repeatable. Its huge plugin ecosystem and flexible pipeline support make it easy to integrate with different tools and adapt to different project needs. It also helps save time by reducing manual steps and making CI/CD workflows more consistent.

It's practically industry standard for an On-Prem installation. If you can run pipelines in the cloud, Jenkins might not be needed, but for those who need it on-prem or local - it's still th best with the biggest community and documentation.

I like that Jenkins is highly flexible and extensive. It is an extensible CI/CD tool with a large plugin ecosystem, which is really helpful. I can customize it to fit almost any build and deployment workflow. The integrations with other tools like Docker, Kubernetes, SonarQube, Artifactory, and Terraform are really good and incredibly flexible. This level of integration allows me to automate infrastructure provisioning, store build artifacts, enable code quality checks, and manage workloads efficiently without needing to switch between multiple tools.
